<code></code>
jQuery:
$("li").each(function () {
words = $(this).text().split(' ');
xxx = words[1]+" "+words[2]+" "+words[3]+",";
$("code").append(xxx);
});
我现在来到这一步,但我不知道如何检查重复日期并附加唯一日期

一种选择是使用:contains
选择器。
$("li").each(function() {
words = $(this).text().split(' ');
xxx = words[1] + " " + words[2] + " " + words[3] + ",";
$("code:not(:contains(" + xxx + "))").append(xxx);
});

这样做: -
if ($("code:contains('"+xxx+"')").length == 0)
$("code").append(xxx);
要处理逗号,请尝试以下方式: -
if ($("code:contains('"+xxx+"')").length == 0){
if ($("code").text() == '')
$("code").append(xxx);
else
$("code").append(","+xxx);
}
要处理此类输出,请尝试以下方式: -
$("li").each(function () {
words = $(this).text().split(' ');
xxx = words[1]+" "+words[2]+" "+words[3];
if ($("code:contains('"+xxx+"')").length == 0){
if ($("code").text() == '')
$("code").append('["'+xxx);
else
$("code").append('","'+xxx);
}
});
$("code").append('"]');

尝试this on jsfiddle,它似乎有效。
